Elatine hungarica Moesz is a small wetland ephemerophyte that occurs and is classified as extinct, data deficient or a very rare and endangered taxon in most countries in eastern and central Europe. Based on literature and herbarium data, supplemented by 160 field records collected between 1998 and 2011, we present the currently known distribution of this species in the Pannonian Basin, which mostly but not exclusively includes Hungary. Within the Pannonian Basin this species is distributed throughout Hungary, with sporadic occurrences in Romania, Serbia and Slovakia. The temporal distribution of floristic records is very uneven. This species was recorded only in 27 years during the last 213 years (1798-2011). When examining presence/absence data for most of the 20th century, we found a significant correlation between the number of records of this species in a given year and two key, but not independent, environmental variables: rainfall and the extent of the area inundated in the same year. In the more intensively documented period between 1998 and 2010, there is only a significant correlation between the numbers of records of this species and the extent of flooding, which is because there is a delay in the effect of an increase in rainfall. The peak occurrence of records in the 1940s and 1950s is associated with extensive rice production in Hungary. Today, most records are for agricultural fields that are subject to flooding and becoming temporary wetlands. The comparison of recent and past distributions of E. hungarica reveals a consistent and marked regional difference; whereas this species is not rare along the Tisza river and its tributaries, it is markedly scattered in similar habitats near the Danube.

Microbial Drug Resistance

This study concerned the occurrence of fecal bacteria with plasmid-mediated quinolone resistance (PMQR) genes in rooks (Corvus frugilegus, medium-sized corvid birds) wintering in continental Europe during winter 2010/2011. Samples of fresh rook feces were taken by cotton swabs at nine roosting places in eight European countries. Samples were transported to one laboratory and placed in buffered peptone water (BPW). The samples from BPW were enriched and subcultivated onto MacConkey agar (MCA) supplemented with ciprofloxacin (0.06mg/L) to isolate fluoroquinolone-resistant bacteria. DNA was isolated from smears of bacterial colonies growing on MCA and tested by PCR for PMQR genes aac(6′)-Ib, qepA, qnrA, qnrB, qnrC, qnrD, qnrS, and oqxAB. All the PCR products were further analyzed by sequencing. Ciprofloxacin-resistant bacteria were isolated from 37% (392 positive/1,073 examined) of samples. Frequencies of samples with ciprofloxacin-resistant isolates ranged significantly from 3% to 92% in different countries. The qnrS1 gene was found in 154 samples and qnrS2 in 2 samples. The gene aac(6′)-Ib-cr was found in 16 samples. Thirteen samples were positive for qnrB genes in variants qnrB6 (one sample), qnrB18 (one), qnrB19 (one), qnrB29 (one), and qnrB49 (new variant) (one). Both the qnrD and oqxAB genes were detected in six samples. The genes qnrA, qnrC, and qepA were not found. Wintering omnivorous rooks in Europe were commonly colonized by bacteria supposedly Enterobacteriaceae with PMQR genes. Rooks may disseminate these epidemiologically important bacteria over long distances and pose a risk for environmental contamination. © 2012 Mary Ann Liebert, Inc. Source

Park in Novi Knezevac was established in the nineteenth century, and it surrounds the manor of Marko Djurkovic - Servijski. During the nineteenth century and early twentieth century further developing of the garden was associated with construction of the manors of Tallián, Feilitzsch and Maldeghem families. Whole park together with the manors of former aristocratic families, two of which have the status of cultural monument, makes unique ambient. Park is located in the old nucleus of Novi Knezevac. West side of park reaches the Tisa river. In this paper landscape-architectural, dendrological, cultural, historical and other values of Park in Novi Knezevac - protected natural monument of garden architecture were analyzed. Analysis of dendroflora was carried out in 2008. As a result 1137 woody plants (238 coniferous and 899 deciduous) within 56 species and lower taxa was recorded. Dendrological parameters of 38 representative trees were measured as well as their decorative features and vitality. The aforementioned parameters are given in table. Based on the analysis of the current state of the park, values, historical genesis and current needs, measures of the protection and promotion, preservation and renewal of the park were proposed. © 2012 Vasile Goldis University Press.

The Metohian Prokletije Mountains are the outermost southeastern branch of interior Dinaric Alps. They are one of the most important centers of floristic diversity of the Balkan Peninsula, with many endemic Balkan species. Source

During field studies of semi-saline meadows and marshes carried out along the Ponjavica River in the vicinity of Banatski Brestovac (Vojvodina, Serbia), we found several specimens of Sporobolus indicus (L.) R. Br. The plant grows in transitional zones between disturbed damp mesotrophic grassland vegetation and semiaquatic communities belonging to the alliance Bolboschoenion maritimi continentale Soó. This adventive and potentially invasive species with a worldwide distribution has never before been recorded in Serbia. Source
